IMPROVEMENT IN FLOUR-SIFTERS.

Specification forming part of Letters Patent No. 169,454, dated November2, 1875 application filed September 11, 1875.

To all whom 'LZ may concern:

Be it known that we, WM. T. LINTNER, MARVIN E. WELLER, and DAYTON S.KEL- LOGG, of Fort Plain, in the county of Montgomery and State of NewYork, have invented a new and valuable Improvement in Flour- Sifters 5and we do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing bad to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked there- The figure ofthe drawings is a representation of a vertical central section of oursieve.

This invention has relation to sieves; and it consists, mainly, in thecombination of a vertically-reciprocating handle, with a coneshapedsifter, all as hereinafter shown and described.

In the annexed drawings, the letter A designates a cone-shapedwire-gauze sifter, which is soldered at its flaring end between a doubleband or rim, a, made of metal, and designed to hold the gauze-work inshape. This sifter is provided with one or more ribs, 11, running on theinside and outside of the gauze-work from the apex to the band a,between which the material of the sifter is permanently soldered, thusendowing the sifter with great rigidity. Ribs b are soldered to rim orat at one end, and to a cone-shaped metallic tip, T, at the other end,which tip forms the apex of the sifter, and prevents it from beingcasually broken. 0 0 represent braces running on the inside of thesifter, which are soldered at the top toband a, and at the bottom to tipT, as are ribs aabove described. These braces are further designed tostrengthenthe sifter, and more effectually guard against its beingbattered or broken. Him a is provided with two perforations, 41 i, theone diametrically opposite the other, the former of which is intended toreceive a hook, d, projecting inwardly from the rim j of a detachablelid, B. This hook serves as a hinge, and is designed to be received inperforation 1 Perforation i receives a projection, e, on a spring-latch,D, on the outside of the flange or rim J of the top B. Top B is of theusual well-known shape, provided in the center with a knob or handle, E,which is endwise movable in relation to the top. The top portionof thisknob is transversely slotted, as shown at s, and is provided with twoperforations, g, on each side, with corresponding perforations Z in thebottom of said knob. These perforations are intended to receive a wirerod, Gr, bent in the form of a staple, and rigidly secured to the top ofthe sieve by means of a plate, a, soldered to the inner side of the topB, to which the said rod is also soldered. H I represent blocks ofrubber, one of which is arranged in the slot 8 in the top of the knob,and the second in the bottom portion of the said knob, for a purposehereinafter described.

The advantage gained by my sifter is, that when flour or othersubstances are to be sifted, the sieve portion may be thrust, tip fore-.most, into a barrel of flour or other substance,

and, by turning it alternately to the right and the left, may be filled;It can then be removed therefrom, and, by taking hold of the handle, andgiving it several percussive blows, the flour will fall therefrom freefrom lumps and grit. Another advantage possessed by my sifter is that,being provided with the rubber deadeners above described, the sound ofthe handle striking against the top of the sifter and the bent portionof the rod is done away with at the time when the percussive blows aregiven to the handle.

What we claim as new, and desire to secure by Letters Patent, is-

l. The combination of a detachable top, B, having flange j, withprojecting hook d, and a spring-catch, D, with the conical sieve A,having rim a, with perforations i i, substantially as specified.

2. The combination, with the sieve A and detachable lid B, of thestaple-shaped rod G, fixed to the latter, and an endWise-movable handle,E, substantially as specified.

3. In combination with a conical sifter, its top B,awire staple-shapedrod, G, and an end- Wise-movable handle, E, the rubber deadeners H T,substantially as specified.

4. The combination, with the conical sieve A, of the solid apexial tipT, substantially as specified.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
